VxWorks target server

hi all.
i have omniswitch 6800 that runs vxworks 5.4.x
The folder that is result of compiling my image consists of :

-rw-r--r--   1 root     other    8128249 Jun 21 05:21 Kbase.img
-rw-r--r--   1 root     other     971810 Jun 21 06:07 Kos.img
-rw-r--r--   1 root     other     295076 Jun 21 06:07 bootrom.bin
-rw-r--r--   1 root     other     866716 Jun 21 06:07 bootrom.hex
-rw-r--r--   1 root     other     607243 Jun 21 06:07 miniboot.backup
-rw-r--r--   1 root     other     607243 Jun 21 06:07 miniboot.default

and my device boot up and works with this !

When i run Tornado and tried to start target server without -c option,

something like tgtsvr.exe 10.0.21.85 -V -B wdbrpc

i got

tgtsvr (10.0.21.85@panasenko): Wed Jun 23 17:45:25 2010
    Checking License ...OK
    Connecting to target agent... succeeded.
    Attaching C++ interface... succeeded.
    Attaching elf OMF reader for PPC CPU family... succeeded.
    Error: Couldn't open D:\Tornado2.2\: status = 0x2
Error during target server core initialization
Target Server will exit

so i go to "Core file and symbols" property page.

And enter the path to Kbase.img.

then i try to start i got

tgtsvr (10.0.21.85@panasenko): Wed Jun 23 17:47:11 2010
    Checking License ...OK
    Connecting to target agent... succeeded.
    Attaching C++ interface... succeeded.

    Error: Object module load failed for D:/Kbase.img
    Error: loading core symbol table: status = 0x1002e
Error during target server core initialization
Target Server will exit

then i tried bootrom.bin and got

    Connecting to target agent... succeeded.

I got similar messages on all files in that directory...
